One for AS here, after beginning the process of finding all my old vinyl stashes in several obscure places around my mansion, I came across a ten inch single by I, Ludicrous. It features the songs Preposterous Tales as the main A side, with Three English Football Grounds and They've Stolen Spocks Brain on the B side.
Orginally released on a flexi disc (kids go and ask you dad) and featured at number 11 in John Peels Festive Fifty of 1987, which can be seen here with samples available.
Other notable charters that I remember well from that year apart from the obvious Smiths, Fall, New Order and Wedding Presents efforts include the remarkable Colorblind James Experience number I am Considering... which notched at number 47.
That is one quality Festive 50.
